Air gap too big
Wrong setting of manual
release
Air gap "s
" too small
L
Rotor has not been replaced
in time
Microswitch incorrectly wired
Microswitch defective or
incorrectly set
Brake voltage does not match
the rectifier
Brake voltage does not match

Microswitch defective or
incorrectly set
Remedy
Check the wiring of the microswitch and correct it.
Replace the complete stator and make a complaint about
the setting of the microswitch to the manufacturer.
Adjust the air gap (

Measure the rotor thickness and compare against the min-
imum rotor thickness (
